Configure PCR2 using the Command Line Interface (CLI)

Install VCP Drivers

To access PCR2 connected with a USB-Cable you need to install the STM VCP drivers first. After installation you should see a new serial device in Windows Device Manger.

Terminal Settings

You then need a Serial Terminal Emulator like Termite or RealTerm to open the serial port.

The CLI uses 57600 8N1 and CRLF (\r\n) line endings.

Here is a video showing how to setup RealTerm.
